SFBD square with a Cummins and custom chassis

Well guys I have encountered my next unknown area that I need to get figured out and I'm hoping you guys can once again save my ass. My Driveline. I've got the slip yoke for the 47RH still attached to the dodge drive shaft. Hopefully I can get it taken apart tomorrow. Will the dodge yoke fit on the Chevy drive shaft?? It looks like the dodge uses a bigger U joint. I figure I'll probably have to shorten my drive shaft which is fine. My plan is to take what I need out of it, butt weld it back together with a good TIG bead, and let the drive line balance it.

Also I need to get my hydro boost buttoned up. I have the high pressure line all connected to the correct place...I think. I have an extra low pressure line though. My hydro boost unit has 2 high pressure lines,the gear box has 1 high and 1 low pressure and the pump has 1 high and 1 low also. So I have a total of 7 connections to make. Not sure how to do this with an odd number of lines lol. The dodge was a vaccuum boost setup off of the vaccuum pump. The Chevy already has hydro boost though and I'd like to keep it that way.

Any help on this stuff would be great. If pix are needed of any of this stuff just let me know. Thanks guy.

i suggest to use the pump from the chevy for the hydroboost that way youre absolutely sure youre brakes work as they should , wish is a nice tought to have when driving around dont you think ?
have the driveline done start to finish by a driveline specialist as they have the tools needed , they might need to thin the end of the yoke on a lathe or fit a bush to make it fit snuhly in the chevy driveshaft before they weld it
to have them make it in the right size you do need to measure between the trans and rearaxle a certan way you have to ask them how to do that and you prolly need to check if theres mush difference between max lift and bottoming out as whell , there was someone on the big forum that even with the correct measurements still had to go back 3 times before they had it the length right 2 where due to him measuring wrong the last one they had made it wrong

The chevy pump should of had 3 lines going to it. 1 pressure and 2 returns. The dodge should have 2. Just t the returns together.

I'm going to try getting a T fitting and plumbing the return lines together and see what kind of result I get. I was reading a guys thread last night off of a goggle search and he brazed an extra return line on his dodge pump. Since their just return lines I'm hoping the T will work. As long as one return doesn't feed back into the other component some how. We'll see I guess.
On the driveline I think since I have 2 shafts and a carrier I can set the carrier bearing up so the rear shaft can remain unaltered. So hopefully just the front shaft will have to be cut. I really don't have the funds to let a driveline shop do the work. I wish I did. It would sure make things a lot easier.

you have to bring it anyway cause the shaft will need rebalancing no mather how you weld it

Just put power steering in a step van that had hydro boost allready tee return. And its working fine. Adding a fitting would be better. Is your motor a p-pump 12 valve? It should've allready had the 16cm housing with a waist gate.

My engine is indeed a P pump but it's got a factory 12cm with a waste gate. The new 16cm non waste gate housing is quite a bigger bigger.

So I stumbled across my stuck Chevy power steering pump with the remote reservoir and all of the factory lines. The pump from the Chevy and dodge are identical other than the Chevy having a remote reservoir. Everything looks exactly the same. I've still got to see if the Chevy pumps shaft will bolt up rogue cummins vaccuum pump. If I can get it bolt to the pump I'll switch them out and be done with it. If not I'll just either T the low pressure houses or add an extra return line. I'd like the use the pump with the remote reservoir also for the extra fluid capacity.

making good progress bro, nice job on the motor mounts btw...

wait ur trying to run air conditioning on ur bagged and bodied cummins swapped dually?

I sure am. I think it can be done with a little extra modifying. I've come this far so why not just do it the way I want the first time.
